HMO Mortgage

HMO Mortgages for Limited Companies vs Personal Ownership

HMO mortgages for limited companies are one of the fastest-growing segments of the buy-to-let market, and one of the most commonly misunderstood. The right ownership structure can save you thousands in tax every year, but the wrong one can trap you in a structure that’s expensive to unwind later. Getting this decision right before you buy is critical, and it’s an area where we frequently advise clients at ABC Finance. 

Two of the main options are limited companies and personal ownership. But choosing the correct vehicle for your property investment isn’t just about preference. There are tax implications, portfolio strategy considerations, personal liability and administration considerations. The structure you choose can also make a big difference in what lenders will offer you. 

Buying an HMO Property as a limited company

Instead of buying a property in your personal name, you can buy it through a limited company, usually a Special Purpose Vehicle (SPV) setup just to acquire and hold property. Generally, lenders prefer SPVs rather than standard trading companies, as the finances are cleaner and easier to underwrite.

With this sort of structure, the company buys the property, and the mortgage is in the company’s name. Then, the rental income flows into the company, rather than the individual. 

Tax

Limited companies aren’t subject to Section 24. This was a tax change introduced in 2017 that removed the ability for landlords in their private capacity to deduct mortgage interest as a business expense. A limited company can still deduct mortgage interest in full, paying corporate tax on the remaining profits. 

The corporate tax threshold currently sits at 25% for profits over £50,000 and 19% for profits below that threshold. For HMO investors with large portfolios, this can represent a large tax saving compared to personal ownership.

Mortgage rates

HMO mortgage rates for ltd company borrowers are typically about 0.1–0.3% higher than rates for properties held in your personal name. Although 0.1-0.3% sounds relatively insignificant, on a £500,000 mortgage, it could work out to an additional £500–£1,500 per year in interest payments.

Administration & Costs

Buying an HMO property as a limited company carries administrative costs and effort you don’t have when buying a property in your personal capacity. You would need company financial statements prepared showing the company’s income, expenses, assets and liabilities. 

Additionally, you’d need to file company tax returns, and basic details of the company (directors, shareholders, registered address) with Companies House, every year. Most people choose to pay an accountant to handle all these affairs, another expense which needs to be accounted for.

Buying an HMO Property in your personal name

If you’re buying an HMO property in your personal name, here’s what you need to consider.

Tax

When buying an HMO in your personal name, the rental income is treated as personal income and taxed at your marginal tax rate. This means the rate is determined by how much income you already earn from other sources, including your job, business income, investments, etc.

The current tax bands in the UK are as follows:

• Basic rate: 20% (income up to £50,270)
• Higher rate: 40% (income between £50,271 and £125,140)
• Additional rate: 45% (income above £125,140)

As already mentioned, HMRC phased in a change in 2017 that removed the ability for individual landlords to deduct mortgage interest as a business expense. 

Before 2017, landlords could subtract their mortgage interest from rental income before calculating their tax bill. Now, landlords with HMOs in their personal name only get a 20% tax credit on mortgage interest, regardless of the tax bracket they fall in.

Mortgage rates

Personal name HMO mortgages normally carry a slightly lower interest rate than limited company mortgages (usually about 0.1-0.3%). Borrowers usually have access to a larger pool of lenders, which ultimately means competitive pricing and more products to choose from. 

However, the stress test applied by lenders is stricter: 145% ICR versus 125% for limited companies. So, although the interest rate is lower, borrowers may actually be able to borrow less against the same property than a limited company.

Administration & Costs

This is where personal ownership has clear advantages over limited company ownership. With personal ownership, there are no company statements to prepare, no Companies House filings, and no corporate tax returns to submit.

There are also no setup or running costs associated with a company. You still do need to submit tax returns, but it’s simpler—and cheaper than running a company.

Comparison of Key Differences: Limited Company vs Personal Ownership

Tax

Personal name landlords pay tax on their rental income at their personal marginal tax rate, which varies between 20% and 45%. They also only receive a 20% tax credit on mortgage interest under Section 24 tax laws. Limited companies pay a lower tax rate (19-25%) and can deduct interest in full.

Mortgage Rates 

When you compare HMO mortgage rates across the market, personal ownership typically offers slightly better interest rates, usually 0.1–0.3% cheaper. However, they are subject to stricter stress tests (125% vs 145%), which means they can borrow less against the same property, compared with limited company ownership.

Administration and Costs

Personal ownership is simpler and cheaper (from an admin perspective). However, an annual self-assessment tax return must still be submitted yearly. This typically costs £200–£500 in accountancy fees. A limited company requires annual accounts, corporate tax returns and Companies House filings, which carry higher accounting costs.

HMO Licensing Requirements for 2026

If you want to own and operate an HMO in the UK, licensing is non-negotiable. In fact, operating a licensable HMO without a valid licence is a criminal offence with serious financial consequences. It directly impacts your ability to get a mortgage, as most lenders won’t loan you money without a valid licence.

The Two Types of HMO Licence

There are two types of HMO licensing to be aware of. Mandatory licensing, which applies across England and Wales to any HMO with 5 or more tenants from 2 or more separate households sharing facilities such as a kitchen or bathroom. This is a non-discretionary licence and applies in every council area, without exception.

Additionally, over 70 councils in England operate additional licensing schemes that extend the requirement to smaller HMOs, typically those with 3 or 4 occupants. 

Several UK cities, including Nottingham, Bristol, Brighton, Newham and Liverpool, operate city-wide additional licensing. This means a 4-bed HMO may need a licence in one council area but not in another.

How Much Does an HMO Licence Cost?

Licence fees are set by individual local authorities and vary considerably across the UK. Fees generally range from £500 to £1,500 for a 5-year licence, although some councils charge significantly more. 

Some councils use a tiered fee structure based on the number of rooms or occupants, and discounts are sometimes available for accredited landlords, early renewal applications or multiple property applications.

The consequences of operating an unlicensed HMO are severe. These include criminal prosecution, penalties of up to £30,000 per offence, and rent repayment orders where tenants can claim back up to 12 months of rent. 

Landlords also lose the ability to serve a valid Section 21 notice, the standard legal route for regaining possession of a property.

How Licensing Affects Your Mortgage

A property without the required licence is effectively unmortgageable with mainstream HMO lenders. Most lenders require a valid licence, or at a minimum, evidence that an application has been submitted, before releasing funds. Licence applications can take 3–6 months to process in busy councils, so this needs to be factored into your purchasing timeline well in advance rather than treated as an afterthought. 

Licensing is one of the most common reasons HMO mortgage applications stall or get declined, particularly if you’re in the dark about the requirements. At ABC Finance, we know each lender’s position on licensing, and we match your case to the lender most likely to approve it first time around.
